Adverse effects of obesity on lipid and lipoprotein levels in insulin-dependent and non-insulin-dependent diabetes.
We studied the association of obesity with lipid and lipoprotein concentrations in 92 patients (49 men, 43 women) with insulin-dependent diabetes (IDDM), in 305 patients (152 men, 153 women) with non-insulin-dependent diabetes (NIDDM), and in 122 nondiabetic control subjects (65 men, 57 women). Obesity (body mass index, BMI) was associated with abnormal lipid and lipoprotein levels only in the presence of diabetes, and lipid and lipoprotein changes were substantially more abnormal in patients with NIDDM than in patients with IDDM. In men and women with NIDDM, obesity was associated with low high-density lipoprotein (HDL) and HDL2 cholesterol and high total, low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) triglyceride concentrations. In men with IDDM, obesity was related only to low HDL and HDL2 cholesterol and in women with IDDM to low HDL3 cholesterol. BMI and diabetes status had a statistically significant interaction (analysis of variance) with respect to HDL and HDL2 cholesterol and total and VLDL triglycerides, indicating that the effects of obesity on lipids and lipoproteins were more severe in patients with diabetes than in nondiabetic subjects. In conclusion, obesity and diabetes status have an unfavorable interaction that results in multiple pathologic lipid and lipoprotein changes, particularly in NIDDM.
